Risks run riot at The Block's challenge apartment

1 of 34Attribution: Nine

It was the shock announcement that left our weary Blockheads with dropped jaws - instead of going home after finishing their apartments, they were to stick around for another two weeks and renovate a secret Gatwick home.

They decided to go with a kooky "St. Kilda" theme, and while some contestants nailed the brief, others certainly did not.

Click through to witness the highs and the horror.

Kerrie and Spence; guest bedroom 1

Final score: 20/30

Kerrie and Spence decided to really embody the “St. Kilda” design brief by wallpapering an entire wall with a graffiti laneway mural.

To say Darren found it disconcerting would be the understatement of the season.

“I feel like I'm falling down a rabbit hole.”

Neale wasn’t a fan of the mural either, saying it was very weird to feel like you’re in bed in a laneway.

Shaynna did make mention that she was glad Kerrie and Spence had finally started to push the envelope.

Darren was having none of that, saying, “If the wall doesn’t give you a headache, the bed head certainly will,” in reference to the potential of hitting your head.

The judges thought the built-in desk was a good inclusion and the best element of the room. Unlike the mural which Darren couldn't get out of his mind.

"I feel like I'm Bart in that Simpsons episode with the creepy clown," he said. "Can't sleep; clown will eat me."

You know the one.

Apart from the mural, the styling choices were on point, however that couldn't help get Kerrie and Spence back in the judges favour.

Jess and Norm; master bedroom

Final score: 20/30

They had the biggest room to renovate this week, but one of the smallest budgets.

Unfortunately it showed, with Darren describing Jess and Norm’s room as “dull.”

Shaynna thought the scale of the room was all wrong.

“What’s with the little rug and the tiny couch?”

Neale was surprised as well. “Norm and Jess usually have great taste, and great flair. None of that is evident in this room.”

The cement-look wall has been used well in the past on The Block, but the judges said Norm and Jess’s version didn’t work and needed a soft bed head in front of it.

Jess’s favourite element of the room, the fireplace, was also deemed a “no” by the judges.

Shaynna was into the “sweet and lovely” salon hang of Block memories.

The walk-in-robe, although executed well, was another missed opportunity according to the judges.

Not least of all because Jess had hidden away artwork that would have been better suited to the bedroom.

Carla and Bianca; ensuite

Final score: 23.5/30

Bianca’s decision to wallpaper the ensuite paid off as soon as the judges walked in.

Shaynna loved it. “It’s fun, it’s quirky. It’s pretty.”

The functionality of the room was praised all round, and the bath placed underneath the window was a huge hit.

“Imagine laying back in the bath and listening to the trams go by.”

The hidden toilet was also appreciated.

Shaynna said the double shower and all glass screen was “sexy.”

However, the lighting design over the vanity was labeled an “epic fail” by Darren.
